I did use Halogen Oven for some years (hinged top types). Very good for cooking BUT did take a large space on worktop. Also although they have a self-clean facility- this is only for the large glass bowl. With each model I found that over time the lid - around the heating element became quite dirty and defied all my effort to clean it. Gave up eventually, and when I moved to a smaller kitchen got rid of my last one.
I fairly recently purchased a small, basic, one drawer AF, and also a silicone liner for this. So, all foods go into that, and it is easily washed up and replaced after each cooking. I do sausages, chips, baked potatoes, chicken breasts/drums ticks, sausage rolls, etc happily in this. I eat quite a lot of fish - and find that something like my salmon fillets are much better cooked in a special dish in my microwave for under three minutes. With my compact AF have not had any problems, with external heat, either onto my granite worktops or under the wall cupboards.
This compact AF is slightly larger than a kettle, I do keep my often used gadgets on my worktop - ease of use is more important to me that trying to keep my kitchen pretending it is a showroom. So, along with this AF, I have slow cooker, toaster, electric egg boiler, soupmaker, and small chopper. (No kettle as I have a special hot water tap),
Do find that I use my main oven very little (usually when I am having people for a meal or cooking cakes), the induction hob is so very fast land efficient, I am not sure which is best (that or microwave), for cooking vegetables.
